not deduce an "overload" type. Such a deduction indicates a failure in
semantic analysis  (e.g., PR5811) that currently isn't caught until
code-generation time. This assertions makes it clearer that this
particular issue is a semantic-analysis problem, not a code-gen problem.

Fix a bug in !subst where TableGen would go and resubstitute text it had
just substituted.  This could cause infinite looping in certain
pathological cases.

Remove uber-gross hack. The define _snprintf to snprintf is invalid due to two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf.

recursing in CGDebugInfo::CreateTypeNode, teach
CanonicalizeTypeForDebugInfo---now called UnwrapTypeForDebugInfo---to
keep unwrapping the type until we hit something that can be
represented by debug information. Thanks to Anders for pointing this out!

and "typeof" nodes, rather than asserting nondescriptly.

two-element arrays.  After restructuring the SROA code, it was not safe to
do this without adding more checking.  It is not clear that this special-case
has really been useful, and removing this simplifies the code quite a bit.

the JIT and Static code generation to an appropriate code model

the underlying PHI node insertion issue in SSAUpdate is fixed.

'GetValueInMiddleOfBlock' case, instead of inserting 
duplicates.

A similar fix is almost certainly needed by the machine-level
SSAUpdate implementation.

implement some optimizations for MIN(MIN()) and MAX(MAX()) and 
MIN(MAX()) etc.  This substantially improves the code in PR5822 but
doesn't kick in much elsewhere.  2 max's were optimized in 
pairlocalalign and one in smg2000.

Use the presence of NSW/NUW to fold "icmp (x+cst), x" to a constant in
cases where it would otherwise be undefined behavior.

Surprisingly (to me at least), this triggers hundreds of the times in
a few benchmarks: lencode, ldecode, and 466.h264ref seem to *really*
like this.

Sema::getTypeName.

"LookupNestedNameSpecifierName" isn't quite the right kind of lookup, though; 
it doesn't ignore namespaces.  Someone more familiar with the lookup code
should fix this properly.
